BACKGROUND OF THE INVENTION

(1) Field of the Invention

The present invention relates to a cooling cabinet, and more particularly, to a cooling cabinet for efficiently removing heat in the cabinet while minimizing affect to the environment.

(2) Description of the Prior Art

The modern life requires a lot of electronic apparatuses such as servers and computers which can be connected with Internet and the servers have high calculation speed and huge storage space so that the computers and servers are used in different types of businesses. In order to manage the servers, the servers are arranged together and installed into a specific room which is equipped with conditioners to cool down the servers which generate heat during use. However, form some small businesses, providing a room for the limited number of servers is not an economy way to use the limited space, so that a cabinet is used to accommodate the servers and the cabinet is equipped with a cooling device.

The conventional cooling cabinet 9 is shown in FIG. 1 and generally includes a space in which multiple electronic devices 91 such as servers or other electronic devices are accommodated. The electronic devices 91 can be received in the cabinet by drawers which slidably received in the space of the cabinet 9. Multiple fans 92 are located in the cabinet 9 so as to generate air flows to remove the heat generated from the electronic devices 91 out from the cabinet 9 and to cool down the electronic devices 91.

The fans suck the air outside of the cabinet 9 into the cabinet 9 and the cooler air absorbs the heat from the electronic devices 91, and the heat air is then brought out from the cabinet 9. However, this way will increase the temperature of the air outside of the cabinet 9 and affects the environment.

The present invention intends to provide a cooling cabinet that mitigate the shortcomings of the conventional cooling cabinets.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 2 to 5, the cooling cabinet of the present invention comprises a cabinet 1, a heat exchange member 2 and an air ventilation member 3. The cabinet 1 has a space 11 for accommodating electronic devices such as servers or other information devices. The space 11 of the cabinet 1 has an opening which is covered by a door 12 which is connected to the opening by a pivotal portion 121. The door 12 has an opening 1021. The door 12 has a recess 122 which is located close to a side of the space 11. The heat exchange member 2 and the air ventilation member 3 are connected in a positioning case 4 and the positioning case 4 is located in the recess 122 and corresponding to the opening 1021. The positioning case 4 includes an outer case 41 and an inner case 42 which is connected to the outer case 41. Each of the inner case 42 and the outer case 41 has slits 411, 421 for ventilation and connection portions 413, 423 for being connected to each other. The outer case 41 has a recessed portion 412 and the heat exchange member 2 is received in the recessed portion 412. The inner case 42 has a recessed portion 422 and the air ventilation member 3 is received in the recessed portion 422. As shown in FIG. 6, the heat exchange member 3 has a refrigerant inlet 241 and a refrigerant outlet 251 so that refrigerant or other liquid that has heat-exchange feature circulates. The air ventilation member 3 is a fan or blower which drives the air flows and fixed to the inner case 42 by the connection rod 31.

As shown in FIG. 6, the heat exchange member 2 has a circulation pipe unit 21 received therein which is heat-conductive and refrigerant flows in the circulation pipe unit 21. The circulation pipe unit 21 has a first pipe group 211 and a second pipe group 212, each of the first and second pipe groups 211, 212 includes multiple parallel circulation pipes. Two respective first ends of the first pipe group 211 and the second pipe group 212 are in communication with each other by a retrieving tube 22, and two respective second ends of the first pipe group 211 and the second pipe group 212 are respectively in communication with a path “A” which uses a separation board 23 to define a entry path 24 communicating with the first pipe group 211, and an exit path 25 communicating with the second pipe group 212. The refrigerant enters the refrigerant inlet 241 and flows through the first pipe group 211 and then flows in opposite direction through the second pipe group 212 by the retrieving tube 22, and exits from the refrigerant outlet 251 to form a circulation.

The air ventilation member 3 sucks the hot air in the space 11 of the cabinet 11 and the hot air passes through the slits 421 and enters into the positioning case 4. The heat exchanges member 2 absorbs the heat in the hot air and reduces the temperature of the air which is then brought out from the cabinet 1 via the slits 411 so that the cabinet 1 is cooled down. The heat that is absorbed by the heat exchange member 2 is brought to a heat releasing device (not shown) located at remote position by the refrigerant flowing through the first and second pipe groups 211, 212. By this way, the impact to the environment is minimized.

FIG. 7 shows the second embodiment of the present invention, which is similar to the first embodiment, the difference is that the door 102 has a larger opening 1021 so that the recess 1022 can accommodate more positioning cases 4 and each positioning case 4 has the heat exchange member 2 and the air ventilation member 3 so as to increase the efficiency of cooling
